bundling optional affiliate software witihin software

Hello,
I have come across certain software bundling certain installers (like the yahoo toolbar, ask toolbar, etc.) within their software products. I was wondering if anyone could direct me to these affiliate programs that let me do such a thing. I believe the developer gets paid per install of those products (maybe a dollar). I have a couple of freeware products online and I would like to monetize them.
also, the affiliate product shouldn’t be shady and should have a good reputation.
Thanks in advance.
